IMPROVED DEVICE FORCLBARING- LAND OF S'IU'IVIPS4 The Schedule referred to iu these Letters Patent and making prt of the same.

,To all 'whom it Imay concern.:

` Be it known that. we, CHARLES CANFIELD and HENDERSON WILLARD, both of' the city of Grand liapids, Kent count-y, lvlichigau, have invented a certain new and useful Method of'ltidding Land ot' Stumps and other obstinate obstructions of wood; and do declare the following to be afull, clear', and exact description thereof'.

Our invention consists in the use of metallic cups and the petroleum of' commerce in its various forms, by means of which stumps and other obstructions oi' wood are prepared for combustion and'con'lpletedestruction by tire, with little labor and small expense.

The manner of applying:y our invention to stumps,

avhere it is chiefiy valuable, is first to drive, sligl'itly,

one or more metalliceups or tubes into the top of' the stump to be operated upon, to receive the petroleum.

These cups may be made of` sheet-iron, in the forni.

of a hollow cylinder, open at both ends, about three inches in diameter and lone,r enough to hohl a quart of liquid.

From one to i'our of these cups may be applied to a stump to advantage, according to size of' stump, and from one to four quarts of' petroleum, crude or refined, or benzine, will be sufiicient to saturate the pores'oi' the stump, and render it highly combustible, in a length ofY time 'arying from three to nine weeks, aecording to the kind ot' woodand its dryness.

The process of' filling the cups after they are adjusted is so simple as not to require explaiuinn. The priming` will soon disappear i'rom the cupsinto the pores of' the wood, when the oups may be removed to other stumps at pleasure.

When `the stump` is; ready to be fired, a light-ed match applied to any part of it, except the bark, will soon wrap it in aiiame that will not cease until every particle ofthe woody fibre, including the roots, shall be consumed. Holes may be bored to receive the priming, but that is slow and laborious.V

These cups, on account of their choapness and the ease and rapidity with which they may be adjusted, and the great number of stumps that one or two ot' them will serve in .one season, render their use a matter of' economy. One or two strokes` of the mallet will iadjust a cup, and one man can adjust the cups ou sev.-

eral hundred stumps in one day.

The work ot' fillinv the cu .is is nearly as l nick and easy. \Vhere a large number ot' stumps are to be primed, a team should be provided to haul the petroleum by the barrell tojthe lmost convenient place or places in the field.

It is economy to provide-each cup with au adjustable cover, to preventwaste of' primiur from evaporation. p

Havingy thus described our invention,

What we claim as new, and desire to secure by lleiters Eitent, is

p The metallic cup, constructed substantially as described, and for the purpose setforth'.

In testimony that we claim the foregoing, we have hereunto set our hands, this 4th day of' March, A. l). 1 869.
